The checkout page[2], in particular, seems designed specifically to trick people into signing up for recurring monthly charges. Any person who adds merchandise to the cart and then clicks the big 'Continue Checkout' button -- without stopping to read all the surrounding text -- will unintentionally sign up for the $39.95/month "VIP" plan.
My mom, who is trusting by nature, would never stop to read all that surrounding text, because she has been conditioned by years of online ordering to add items to a cart and then find and click the big checkout button. She would be tricked into signing up for recurring charges.
